Willink is a senior research biologist at the Shedd Aquarium, and so he often visits the shoreline to check on the health of the lake.</p><p>&ldquo;Something I like to do is whenever I go out, I try to do as many things at once: monitoring invasive species, looking for endangered species and just sort of assessing the community on the Chicago Lakefront,&rdquo; Willink said.</p><p>And from the surface, it&rsquo;s impossible to see it all. According to Willink, at any given spot, there could be tens of thousands of fish swimming around: A little-known fact for many local swimmers. Another example: Willink said there are likely quadrillions of invasive zebra mussels and quagga mussels in Lake Michigan.</p><p>You can hear their dead shells crunch as you walk along the shore.</p><p>This year, Willink said, he&rsquo;s stumbled on a few species that he isn&rsquo;t as used to seeing, like Coho salmon, perch and bloaters&mdash;all fish that favor cooler, deeper waters.</p><p>&ldquo;When the bloater showed up it was like &lsquo;oh, okay, something&#39;s really going on,&rsquo; because I think in the past 10 years, I&rsquo;ve only caught one other bloater in a net,&rdquo; Willink said. &ldquo;So catching a half-dozen of them really meant that something different was going on.&rdquo;</p><p>On average, temperatures in Lake Michigan this summer have been much cooler than normal. According to data from the <a href="http://coastwatch.glerl.noaa.gov/webdata/cwops/html/statistic/statistic.html%20" target="_blank">National Oceanic and Atmospheric Administration</a>, surface temperatures have been about 2.75 degrees Celsius below average. The managers of this data believe that&rsquo;s likely because of all the ice cover that came along last winter. The Great Lakes were at least 90 percent ice covered last winter, and that hasn&rsquo;t happened since 1994.</p><div class="image-insert-image "><img alt="" class="image-original_image" src="http://www.wbez.org/system/files/styles/original_image/llo/insert-images/avgtemps-m_1992-2013.gif" title="" /></div><p>Willink said all that cooler water encouraged fish that usually stay deep, deep down in the lake to swim up to the surface.</p><p>&ldquo;Everybody thought it was a harsh winter, and we&rsquo;d have fewer fish. I&rsquo;ve actually found more this year,&rdquo; Willink said. &ldquo;It may very well be that Great Lakes fish like harsh winters, because after all, that was a much more typical winter.</p><p>But some other fishermen aren&rsquo;t so sure of that connection.</p><p><img alt="" class="image-original_image" src="http://www.wbez.org/system/files/styles/original_image/llo/insert-images/cpt%20rick%204.jpg" style="height: 400px; width: 300px; float: left;" title="Captain Rick Bentley, owner of Windy City Salmon Fishing Charters. (WBEZ/Lauren Chooljian)" />Captain Rick Bentley is the owner of <a href="http://www.windycitysalmon.com/" target="_blank">Windy City Salmon Fishing Charters</a>. He takes groups fishing off Waukegan Harbor in Lake Michigan, so thriving fish make for better business. And he said this spring, the Coho salmon fishing was the best he&rsquo;s ever seen.</p><p>&ldquo;It was excellent. A lot of times in April, we&rsquo;re waiting for Coho to get here. They typically mass up in schools on the way extreme south end of the lake,&rdquo; Bentley said. &ldquo;But we had them right at the beginning of April when we started fishing.&rdquo;</p><p>Bentley said he remembers all the ice cover. It covered the harbor until April 10th, which he said is unusual. But he&rsquo;s not convinced the two things are related.</p><p>&ldquo;You need to have several of those winters in a row, and we really haven&rsquo;t had a winter like that in a while,&rdquo; he said. &ldquo;So whether it was due to the winter, we&rsquo;ll have to see about that.&rdquo;</p><p>According to&nbsp;<a href="http://www.lsa.umich.edu/pite/people/facultyassociates/ci.gadenmarc_ci.detail" target="_blank">Marc Gaden</a> of the Great Lakes Fishery Commission, Captain Rick Bentley may not get the chance to make that assessment. Gaden worked on this year&rsquo;s <a href="http://www.globalchange.gov/what-we-do/assessment" target="_blank">national climate change report</a> and he said all the research points in the opposite direction of the thermometer.</p><p>&ldquo;The downward trend is quite unmistakable since the 1970s. And so we&rsquo;ll see fewer and fewer winters where we&rsquo;ll have that significant amount of ice cover in the Great Lakes basin, that&rsquo;s clear from the trends. And the models of climate change scenarios suggest that&rsquo;s not going to change,&rdquo; Gaden said.</p><div class="image-insert-image "><img alt="" class="image-original_image" src="http://www.wbez.org/system/files/styles/original_image/llo/insert-images/m2013_2014_ice.gif" title="" /></div><p>And in the decades to come, Gaden said that could, among many other things, make the lakes &ldquo;quite an inviting place to some of the invasive species that we&rsquo;re very concerned about like Asian Carp.&rdquo; According to Gaden, that warmer water could also lead to an expansion of species like sea lamprey, quagga and zebra mussels that are already in the lake.</p><p>Back at 63rd Street Beach, Willink said on the one hand, sometimes people tend to forget that the Great Lakes are always changing and they always have been: Fish, animals and plants have survived both warm and cold years before. And, he adds, it is hard to really know how one pattern will affect the ecosystem long term.</p><p>But since this has been an unprecedented rate of change, how the fish will respond is an open question.</p><p><em>Lauren Chooljian is a WBEZ reporter.

(Tim Schroeder/TWS Photography)" /></div><p>The Great Lakes have been facing some serious challenges, from algae blooms in Lake Erie, to the loss of ice cover in Lake Superior. Water levels in lakes Michigan and Huron have been mostly below their long-term average for fifteen years. <a href="http://www.wbez.org/news/what-happens-if-water-lake-michigan-keeps-disappearing-104748">At the start of 2013, they hit record lows</a>, but a long winter with a lot of snow and ice has brought the lakes back up.</p><p>Michigan and Huron, which rise and fall together and have been the hardest-hit by the low water, peaked <a href="http://www.glerl.noaa.gov/data/dashboard/GLWLD.html">just around their long-term average in July</a> (although they&rsquo;re still several inches below their average for this time of year, when the water is typically highest). If the levels in Michigan-Huron stay above the overall average, it will be the first sustained rise since 1998.</p><p>WBEZ has reached out to scientists, fishermen, shippers &mdash; anyone who could shed light on what&rsquo;s happening. It turns out, some of the sharpest observers of the lake&rsquo;s wild swings the last few years are artists. We talked to a photographer and a landscape painter, both of whom look at the same lake, but don&rsquo;t necessarily see the same things.</p><div class="image-insert-image "><img alt="" class="image-original_image" src="http://www.wbez.org/system/files/styles/original_image/llo/insert-images/Lewis-Pier-Photo.jpg" title="Tim Schroeder is a photographer and long-time resident of St. Joseph, Michigan.

Tim Schroeder says he comes down here all the time to take pictures, or just to observe.</p><p>&ldquo;I&rsquo;ve done a lot of photographs of fishermen and stuff on the pier, just the mood of the lake, the atmosphere,&rdquo; he says. Schroeder, 62, has been a <a href="http://www.twsphotography.com/">professional photographer</a> in St. Joseph for 40 years.</p><p>The lakefront is always changing, and Schroeder&rsquo;s photographs show that. They&rsquo;re kind of eerie, mystical photos featuring rocks jutting out into misty skies, the remnants of rotting piers.</p><div class="image-insert-image "><img alt="" class="image-original_image" src="http://www.wbez.org/system/files/styles/original_image/llo/insert-images/SCHROEDER_WBEZ_1.jpg" title="A photo of Lake Michigan from Tim Schroeder’s collection (Tim Schroeder/TWS Photography)" /></div><p>&ldquo;I can see things now that may not have even been visible before, old pilings, breakwaters, stuff like that,&rdquo; says Schroeder. He says the low water has revealed a lot of visually interesting things that use to be submerged.</p><p>Further north in Michigan, <a href="http://maryeandersen.com/art/">painter Mary Andersen</a> keeps a studio in Grand Rapids. Her house is full of her impressionistic, abstract paintings of the lakeshore, all pale colors and light.</p><p>She often goes back to the same spot over and over as it changes, and just like Tim Schroeder, Andersen has been watching the lake her whole life.</p><p>&ldquo;I grew up looking at it, swimming in it, traveling to the beaches,&rdquo; Andersen says.</p><p>She loves how the shoreline shifts and moves, she says. &ldquo;I find it interesting and exciting. If it was always the same, how boring.&rdquo;</p><div class="image-insert-image "><img alt="" class="image-original_image" src="http://llnw.wbez.org/styles/original_image/llo/insert-images/Mary-Andersen-Pic-1.jpg" title="Painter Mary Andersen isn’t particularly worried about the water levels fluctuating. (Lindsey Smith/Michigan Radio)" /></div><p>Schroeder agrees: The constant transformation is inspiring. But back out at the lakefront, he gestures towards a stepladder that goes off the edge of the pier. It&rsquo;s the kind you climb down to get in for a swim, but we&rsquo;re still yards from the actual water and the ladder goes straight into the sand.</p><p>This change &mdash; the water receding &mdash; makes Schroeder uncomfortable.</p><p>&ldquo;I don&rsquo;t like seeing the lake levels lower, because I think it&rsquo;s a little unnerving,&rdquo; he says. Like a lot of folks, Schroeder&rsquo;s not exactly sure why the water tends to be lower these days.</p><p>Part of it may be man made; a shipping channel on the other side of Lake Huron has been deepened over and over to keep it passable. Most researchers agree that&rsquo;s <a href="http://www.jsonline.com/news/wisconsin/once-steady-great-lakes-flow-altered-by-dredging-dams-and-now-warming-temperatures-217150821.html">lowered Lake Michigan and Huron by 10-18 inches</a>. In general though, <a href="http://www.wbez.org/news/what%E2%80%99s-causing-record-low-levels-lake-michigan-105262">lake levels fluctuate based on climate: precipitation and evaporation</a>. The record lows in 2013 were caused by a hot summer and drought, and this past winter&rsquo;s <a href="http://www.wbez.org/series/curious-city/just-how-bad-chicago-winter-109637">Polar Vortex</a>, complete with loads of snow and ice, helped bring them back up.</p><p>But now some scientists are saying droughts and lack of ice cover could cause Lakes Michigan and Huron to stay low over the long run. The Council of the Great Lakes Region (CGLR) <a href="http://councilgreatlakesregion.org/projects/low-water-blues/">commissioned a study</a> of a worst-case scenario.</p><p>&ldquo;If we were to see a future, as a result of climate change where water levels in the Great Lakes region would be at their lows for an extended period of time, what would the economic impact be?&rdquo; asks Mark Fisher, CEO of the CGLR.</p><p>The report finds cargo ships would have to reduce their loads for every inch the lakes go down. There are also costs for the exposed and rotting infrastructure Schroeder likes to photograph; tourism and the region&rsquo;s indigenous communities would take a hit, and lakefront property values could also suffer.</p><p>Between now and 2030, the report estimates a potential economic loss of $9.6 billion in the U.S. and Canadian areas surrounding the Great Lakes. By 2050, it would add up to almost $19 billion across the region.</p><p>This is just one scenario, and water levels are difficult to predict beyond about 6 months out. But Fisher says many of the estimates are conservative, and regardless, we need to look at the short-term changes as part of a bigger picture.</p><p>&ldquo;The challenge with climate change is that it&rsquo;s subtle, it&rsquo;s incremental. It&rsquo;s sometimes hard to see depending on where you are in the basin,&rdquo; he says.</p><div class="image-insert-image "><img alt="" class="image-original_image" src="http://www.wbez.org/system/files/styles/original_image/llo/insert-images/Mary-Andersen-Pic-2.jpg" title="Mary Andersen does most of her painting in her home in Grand Rapids, but she also spends hours at the lakeshore observing. (Lindsey Smith/Michigan Radio)" /></div><p>But not everyone is worried about all this &mdash; artist Mary Andersen knows the lake better than most, and she says last year&rsquo;s record low water didn&rsquo;t faze her. &nbsp;</p><p>&ldquo;Because I grew up along the lake, I have witnessed the fluctuation in the lake levels three times over my lifetime, from severe lows to record highs,&rdquo; she says.</p><p>In fact, she remembers extremely high water in the 1980s being destructive in its own way, causing erosion on the lakefront, and sometimes flooding low-lying areas.</p><p>Andersen says she is worried about <a href="http://www.wbez.org/series/front-and-center-water/drought-drives-drilling-frenzy-groundwater-california-110483">water scarcity and drought in other places</a>, but she&rsquo;s not sure about climate change. She thinks the lake&rsquo;s changes are a natural cycle.</p><p>&ldquo;The fluctuation of the lake levels is not our fault,&rdquo; Andersen says.</p><p>When it comes to fluctuation, most scientists would agree that it is a natural cycle: <a href="http://www.glerl.noaa.gov/data/dashboard/GLWLD.html">The levels have gone from low to high every 10-25 years</a> since humans started recording it about 100 years ago. &nbsp;The concern is that climate change could mean the lows keep getting lower, and the highs never get quite as high.</p><p>But the extremes associated with climate change means it&rsquo;s difficult for scientists to predict; after all, in the middle of winter 2012-2013, no one had any idea the lake levels would <a href="http://w3.lre.usace.army.mil/hh/ForecastData/MBOGLWL-mich_hrn.pdf">rise by several feet in just over a year.</a></p><p>And, lower water levels is only a piece of what could be coming to the Great Lakes.</p><p>&ldquo;It almost feels like death by a thousand cuts to the Great Lakes region,&rdquo; says Beth Gibbons, the project manager with the Great Lakes Climate Change Assessment for Cities (GLAA-C) in Ann Arbor. &nbsp;</p><p>Gibbons is focused on adaptation and preparedness for climate change. &ldquo;We can&rsquo;t wait for a single event &mdash; sea level rise to pass &lsquo;X&rsquo; threshold, a Hurricane Sandy to come up the coast, a wildfire that&rsquo;s burning 800 acres to suddenly threaten one of our major cities. We need to be able to look at this day by day, storm by storm.&rdquo;</p><p>She says we need <a href="http://graham.umich.edu/glaac/great-lakes-atlas">to take stock of what&rsquo;s coming</a> in order to plan for more climate extremes.

They are.&nbsp;</em></p><p>A couple summers ago, Cherelyn Riesmeyer took her kids to a Chicago beach. They had brought their new boogie boards along, which they&rsquo;d purchased on a family vacation a few weeks earlier.</p><p>But when they leapt into Lake Michigan with their new beach toys, Cherelyn says, a lifeguard promptly told her kids that boogie boards weren&rsquo;t allowed on Chicago beaches.</p><p>&ldquo;[My kids] starting referring to the lifeguards as <em>fun guards</em>,&rdquo; Cherelyn says.</p><p>Then, in January 2012, a local surfer was <a href="http://www.wbez.org/story/charges-be-dropped-against-chicago-surfer-96500" target="_blank">arrested for illegally surfing</a> at Oak Street Beach. When Cherelyn heard the news, she says, she was in disbelief. But she also wanted answers, so she asked Curious City:</p><p dir="ltr" style="text-align: center;"><em>Why is surfing not allowed in Lake Michigan?</em></p><p>Turns out, surfing<em> is</em> allowed in Lake Michigan, but it wasn&rsquo;t always, and even now it&rsquo;s not allowed everywhere. In 2009, the Chicago Park District lifted its blanket ban on surfing and all &ldquo;self-propelled, wave-riding board sports.&rdquo; These include: body surfing, stand-up paddling, skim boarding and &mdash; of particular interest to our question-asker &mdash; boogie boarding. The district made the decision after local surfers and activists took a stand against the restrictions.</p><p>One of those activists was Mitch McNeil, chair of <a href="http://www.chicago.surfrider.org/#welcome" target="_blank">Chicago&rsquo;s Surfrider Foundation</a>. He recalls the park district had banned surfing and all flotation devices after a 10-year-old girl drowned off Montrose Harbor in 1988. The girl and an 11-year-old boy were on an inflatable raft when the wind blew them far offshore, according <a href="http://articles.chicagotribune.com/1988-04-07/news/8803060938_1_windsurfer-raft-lake-michigan" target="_blank">to a report in the Chicago Tribune</a>. The two apparently jumped off the raft and tried to swim back to the beach. A nearby windsurfer rescued the boy but couldn&rsquo;t find the girl.</p><p>&ldquo;The city reacted drastically [after the incident] and put an across-the-board ban on flotation devices,&rdquo; McNeil says. &ldquo;And a surfboard is nothing else if not a flotation device.&rdquo;</p><p>About two decades later, Chicago-area surfers banded together to reverse the ban, McNeil says. An agreement they worked out with the city lifted the ban on a handful of beaches, but there was an important condition: surfers would be responsible for their own safety.</p><p>So today, surfing is allowed year-round at <a href="http://www.cpdbeaches.com/beaches/Montrose-Beach/" target="_blank">Montrose </a>and <a href="http://www.cpdbeaches.com/beaches/57th-Street-Beach/" target="_blank">57th Street</a> beaches. During the off-season (Labor Day to Memorial Day), surfing&rsquo;s allowed at <a href="http://www.cpdbeaches.com/beaches/Osterman-Beach/" target="_blank">Osterman </a>and <a href="http://www.cpdbeaches.com/beaches/Rainbow-Beach/" target="_blank">Rainbow </a>beaches, too.</p><p>It may seem like a short list (consider that <a href="http://www.cpdbeaches.com/home.cfm" target="_blank">the district operates 27 public beaches</a>), but Mcneil says he and other Chicago surfers are satisfied with the compromise &mdash; at least for now. Turns out, those four beaches get some of the best waves in the city (which can get up to 30 feet high!).</p><p>&ldquo;Each beach has its own kind of wave,&rdquo; McNeil says. &ldquo;Each wave is created by the way the bottom is shaped and how the shoreline is lined up according to the wind. So, we had our hit list.&rdquo;</p><p>Also, it&rsquo;s no bummer there are more beaches to choose from in the winter.</p><p>&ldquo;That&rsquo;s actually when the best waves happen,&rdquo; McNeil says. &ldquo;You get your best waves in the fall and definitely in the winter.&rdquo;</p><p>But there&rsquo;s good news for Cherelyn, our question-asker, too. Since the park district includes boogie boarding in its definition of surfing, the same rules apply. So those &ldquo;fun guards&rdquo; her kids encountered? Well, the story could have been different at a different beach.</p><p>For specifics on Chicago&rsquo;s surfing and flotation device regulations, you can also read <a href="http://public.surfrider.org/files/Chicago_Surfing_Info_Safety.pdf" target="_blank">this 2009 memo</a> from the Chicago Park District.</p></p> Fri, 15 Aug 2014 16:45:00 -0500 http://www.wbez.org/series/curious-city/surfs-chicago-where-110665 Great Lakes brace for more toxic algae http://www.wbez.org/news/great-lakes-brace-more-toxic-algae-110112 <p><p><em>Update, August 4, 2014, 11:30a.m.: Officials are scrambling to address a growing algae bloom in Lake Erie that threatens the water supply of hundreds of thousands of people in parts of Michigan and Ohio. After tests at a water treatment plant showed dangerous levels of contamination, Toledo, Ohio officials&nbsp;warned residents not to use city water early Saturday. The water ban was lifted Monday, but the algae bloom isn&#39;t expected to peak until September, potentially continuing to pollute the lake that supplies drinking water for 11 million people.&nbsp;</em></p><p>It&rsquo;s spring, and the heavy snowmelt and rain is good news for farmers and scientists who have been worried about drought the last few years. But all that water has other consequences for the Great Lakes, including runoff: rainstorms carry fertilizer from farms and lawns into streams and rivers.</p><p>Much of it eventually ends up in the lakes, and when too much accumulates it can feed huge blooms of toxic algae. The problem is especially dire in Lake Erie around Toledo, Ohio, where algal blooms in 2011 and 2013 were some of the worst on record.</p><p>&ldquo;I&rsquo;ve seen the lake go from where you weren&rsquo;t even supposed to go swimming in it to what it&rsquo;s like today, and the change has been phenomenal,&rdquo; says Tim Robinette, a Toledo-area resident and longtime fisherman. &ldquo;There were places that used to literally dump their waste in the river, and it used to float on down the river back in the &lsquo;50s and &lsquo;60s. And that don&rsquo;t happen anymore.&rdquo;</p><p>Lake Erie became infamous for its contamination after the <a href="http://www.google.com/url?q=http%3A%2F%2Fwww.cleveland.com%2Fscience%2Findex.ssf%2F2009%2F06%2Fcuyahoga_river_fire_40_years_a.html&amp;sa=D&amp;sntz=1&amp;usg=AFQjCNFrwLjBkRSrEfOZxS0CiBu_HPNmSQ">Cuyahoga River caught on fire in 1969</a>; the lake&rsquo;s notoriety is credited with inspiring the passage of the federal Clean Water Act as well as the creation of Earth Day. And Lake Erie&rsquo;s comeback has been equally legendary: point source pollution from factories and sewage systems was cleaned up to a great extent by the 1990s.</p><p>In the 2000s, though, algal blooms began to reappear in the lake, bringing with them dead zones, bad smells and water that was once again risky to consume even in small amounts. In 2011, following a spring of particularly extreme rains, the algae blooms in Lake Erie grew to more than 5,000 square kilometers&mdash;three times the previous record. That got the attention of the International Joint Commission, the U.S. and Canadian body that has monitored the lakes for more than a century. They worked on <a href="http://www.google.com/url?q=http%3A%2F%2Fwww.ijc.org%2Ffiles%2Fpublications%2F2014%2520IJC%2520LEEP%2520REPORT.pdf&amp;sa=D&amp;sntz=1&amp;usg=AFQjCNEL7GD6q-OXSzaquvJC8_DaPA47IQ">a major report</a> released this spring urging states and provinces to take immediate action to curb runoff.</p><p><strong>The green goblin</strong></p><p>&ldquo;Well, it looks kind of like green goo, you know, like thick, like pea soup-type green,&rdquo; says Carol Stepien, a biologist at the University of Toledo&rsquo;s Lake Erie Center, which overlooks the Maumee Bay.</p><p>The gooey muck she&rsquo;s talking about is blue-green algae or cyanobacteria, which, when it&rsquo;s overfed by fertilizers in the water, can grow into blooms that are dangerous to drink or even touch. In recent years cyanobacteria has poisoned multiple pets who drank from the lake, and last summer it <a href="http://www.google.com/url?q=http%3A%2F%2Fwww.toledoblade.com%2Flocal%2F2013%2F09%2F15%2FCarroll-Township-s-scare-with-toxin-a-wake-up-call.html&amp;sa=D&amp;sntz=1&amp;usg=AFQjCNFoUOuLh5_aFgTbMxEWSmrMHbEGTA">shut down a water treatment system in a township near Toledo</a>.</p><p>When the algae decomposes there&rsquo;s another problem: it eats up oxygen, and that creates dead zones in the lake where no fish or plants can live, an effect called hypoxia.</p><div class="image-insert-image "><img alt="" class="image-original_image" src="http://www.wbez.org/system/files/styles/original_image/llo/insert-images/Copy%20of%20DSCN1768.JPG" style="height: 210px; width: 280px; margin-left: 5px; margin-right: 5px; float: right;" title="The Maumee River runs from the west through Toledo and into Lake Erie, carrying fertilizer runoff from rural and urban sources with it." /></div><p>Stepien explains that the Maumee River, a large river that runs through the middle of Toledo and into the bay, carries fertilizer runoff from up to 150 miles away. The Maumee Bay is a particularly warm, shallow part of the lake, and as runoff gathers, the algae becomes a well-fed monster.</p><p>But this isn&rsquo;t some mysterious green goblin. Stepien says the problem can be traced primarily to phosphorus, an ingredient in commercial fertilizers that&rsquo;s also found in manure, and sewer overflows from municipal water systems. The trouble is identifying and stemming the sources of the phosphorus.</p><p>&ldquo;This is water that&rsquo;s coming in from many many places, it can&rsquo;t be pinpointed to a single pipe or certain pipes,&rdquo; she says.</p><p><strong>Golf greens can&rsquo;t be brown</strong></p><p>Sources can&rsquo;t be pinpointed individually, but the potential sources are widely known. Among them are lawns and golf courses that use commercial fertilizers. Just a couple miles away from the lake, there&rsquo;s a golf course right along the river.</p><p>&ldquo;Golf courses get a bad rap for the leaching issue,&rdquo; says Tim Glorioso, the golf course manager at the Toledo Country Club. He admits people who come here don&rsquo;t want their greens to be brown, and a <a href="http://www.google.com/url?q=http%3A%2F%2Fwww.eifg.org%2Fwp-content%2Fuploads%2F2012%2F07%2Fgolf-course-environmental-profile-nutrient-report.pdf&amp;sa=D&amp;sntz=1&amp;usg=AFQjCNEgmkTGFSZ4oHA9FXxlx8sHFw-UGg">2009 survey of golf course managers</a> found the average golf course puts down 65 pounds of phosphorus per acre each year, and even more pounds of nitrogen.</p><p>Glorioso, though, says he uses a lot less.</p><p><img alt="" class="image-original_image" src="http://llnw.wbez.org/styles/original_image/llo/insert-images/Copy of DSCN1661.JPG" style="height: 201px; width: 280px; margin-left: 5px; margin-right: 5px; float: left;" title="Tim Glorioso is the director of golf course operations at the Toledo Country Club." />&ldquo;With the way budgets are right now, why would you go out and put more phosphorus down and more nitrogen than you need to? It doesn&rsquo;t make sense, economically,&rdquo; he says.</p><p>Glorioso monitors the phosphorus in the soil constantly, and says he only puts on the amount the grass can absorb. Timing matters too &mdash; simple stuff like not putting down nutrients on frozen ground, or right before a storm. He attends continuing education classes during the winter months and thinks responsible management practices can lessen golf courses&rsquo; contribution to the algae problem. But he admits that not everyone is quite so diligent.</p><p>&ldquo;We have some people that probably don&rsquo;t do what they&rsquo;re supposed to do,&rdquo; he says.</p><p><strong>Some farmers resist regulation</strong></p><p>Most of the area that drains into the Maumee River isn&rsquo;t golf courses or suburban lawns: it&rsquo;s farms. There are miles and miles of them &mdash; mainly corn, wheat and soybeans &mdash; from Toledo all the way up the Maumee River and its tributaries, which extend into Indiana and Michigan.</p><p>&ldquo;We could argue back and forth about is it urban, is it yards, is it agriculture, is it municipal water systems,&rdquo; says Tadd Nicholson with the Ohio Corn and Wheat Growers Association. &ldquo;I prefer to say it&rsquo;s all of those things.&rdquo;</p><p>Corn has been booming recently due to ethanol production, so farmers are planting to the very edges of fields, and at least some of them are laying the fertilizer down thick. But Nicholson says the corn industry is producing more corn per acre while also using less fertilizer than it did a few decades ago. In other words, corn can&rsquo;t be solely to blame for the resurgence of algal blooms. And, like Glorioso, he says education and voluntary programs to reduce runoff are as beneficial for the industry as they are for the lake.</p><p>&ldquo;If we can show farmers how to minimize phosphorus runoff, it&rsquo;s not a hard sell, it&rsquo;s something that we are very motivated to do,&rdquo; he says.</p><p>It&rsquo;s worth noting that over-applying fertilizer isn&rsquo;t against any laws in Ohio, and agriculture in particular has long been <a href="http://www.google.com/url?q=http%3A%2F%2Fwww2.epa.gov%2Fsites%2Fproduction%2Ffiles%2F2014-03%2Fdocuments%2Fcwa_ag_exclusions_exemptions.pdf&amp;sa=D&amp;sntz=1&amp;usg=AFQjCNFYv09n7PPIYQ7Xb7QphYUC8zJFTA">exempted from aspects of the Clean Water Act</a>; the industry has also pushed back against water quality regulations for runoff.

It has the support of the Ohio Farm Bureau, but not the Ohio Corn and Wheat Growers Association. And even that law is not really a set of rules but a required educational program. In Illinois, a 2010 law restricting the use of phosphorus in fertilizer exempts farms and golf courses.</p><div class="image-insert-image "><img alt="" class="image-original_image" src="http://www.wbez.org/system/files/styles/original_image/llo/insert-images/Copy%20of%20DSCN1775.JPG" title="Runoff into the Maumee River comes from diffuse sources: urban stormwater and sewer overflows, agricultural runoff, and private lawns and golf courses." /></div><p><strong>&lsquo;When you look at Lake Erie, it breaks your heart&rsquo;</strong></p><p>Cities like Chicago and Toledo are under federal order to reduce sewer runoff&nbsp; through extensive infrastructure upgrades, and manure runoff, which is also a contributor, is more tightly regulated than farms. The IJC report finds the need for more research and monitoring to establish clear best practices for reducing runoff from all sources, and the agriculture industry in particular has posited the need for more research as a reason to hold off stringent regulation.</p><p>&ldquo;We would never allow a dump truck full of manure to back up and dump into the lakes,&rdquo; says Lana Pollack, the U.S. chair for the IJC. She refutes the idea that there&rsquo;s not enough research to take action on the issue. &ldquo;The science is there, we understand the cause, we understand the effect, and we understand that no one should have a choice whether or not to harm Lake Erie or any of the other lakes.&rdquo;</p><p>Lake Erie is far from the only body of water that&rsquo;s been affected: smaller lakes throughout the region have seen algae blooms in recent years. Last year, the bay of Green Bay Wisconsin was literally green. And there may not be an algae bloom off Chicago&rsquo;s Navy Pier yet, but that&rsquo;s because <a href="http://www.google.com/url?q=http%3A%2F%2Fillinois.sierraclub.org%2Fconservation%2Fwater%2Fnutrients.pdf&amp;sa=D&amp;sntz=1&amp;usg=AFQjCNH9Lknjq4XxrRhehMxjWLvrrn85Lw">most of Illinois&rsquo; runoff drains to the Gulf of Mexico</a>. In the past, that&rsquo;s helped create a dead zone there larger than the state of New Jersey. Smaller lakes and ponds throughout the midwest are susceptible to algal blooms during the summer months.</p><p>Climate change is also intensifying the algal blooms. Algae prefer warmer temperatures, and more intense rainstorms mean more intense runoff.</p><p>The <a href="http://www.google.com/url?q=http%3A%2F%2Fwww.ijc.org%2Ffiles%2Fpublications%2F2014%2520IJC%2520LEEP%2520REPORT.pdf&amp;sa=D&amp;sntz=1&amp;usg=AFQjCNEL7GD6q-OXSzaquvJC8_DaPA47IQ">IJC report</a> recommends that Ontario, Canada and the states in the Lake Erie basin set new targets for reducing phosphorus runoff in Lake Erie. That could lead to more regulation on farms as well as septic system owners and urban water treatment systems.</p><p>&ldquo;One community shouldn&rsquo;t be able to decimate the resources that are so important to everyone,&rdquo; Pollack says. &ldquo;If you look at Lake Erie, it breaks your heart.&rdquo;</p><p>She also says there&rsquo;s no silver bullet, no single solution or single cause.

(Photo courtesy of Aaron Stigger)" /></div><p><font><font>It&rsquo;s not just a problem in Chicago. Humans move a lot of salt. A 2004 study estimated that we mobilize more than 140 teragrams &mdash; that&rsquo;s 140 billion kilograms &mdash; of chlorides every year.</font></font></p><p style="text-align: center;"><font><font><strong>Video: </strong><a href="#video">Just how big are these salt piles</a>?</font></font></p><p><strong><font><font>Salt&rsquo;s destination: our streams and rivers</font></font></strong></p><p><font><font>So, with some of these figures in mind, let&rsquo;s consider the effects.</font></font></p><p><font><font>Aaron Stigger&rsquo;s &ldquo;aha moment&rdquo; came about when he saw one of the city&rsquo;s salt piles while it was uncovered. It&rsquo;s a reasonable concern, given that researchers from the University of Rhode Island </font></font><a href="http://www.uri.edu/ce/wq/ww/Publications/Chlorides.pdf" target="_blank"><font><font>estimate uncovered salt piles lost about 20 percent</font></font></a><font><font> of their salt each year. Much of it ends up in nearby waterways.</font></font></p><p><font><font>Most piles are covered during the off-season, however, so salt used for deicing is the main source of urban chloride pollution. Chemists know salt as NaCl, or sodium chloride, which breaks down in water. Hence there are pollution measurements and standards for &ldquo;chlorides,&rdquo; not &ldquo;salt.&rdquo;</font></font></p><p><font><font>But where&rsquo;s this runoff headed? The hydrological lay of the land is such that most salt-laden runoff in Chicago ends up in the Chicago River and other inland waterways &mdash; not Lake Michigan.</font></font></p><p><font><font>The principal reason is that </font></font><a href="http://chicagopublicradio.org/story/should-we-reverse-chicago-river-again-95661" target="_blank"><font><font>the city reversed the flow of the river more than 100 years ago</font></font></a><font><font>, so most of our runoff ends up in the waterways that feed into the Illinois River, which flows into the Mississippi and eventually the Gulf of Mexico.</font></font><a href="http://www.isws.illinois.edu/pubdoc/B/ISWSB-74.pdf" target="_blank"><font><font> A 2010 study from the University of Illinois at Urbana-Champaign found</font></font></a><font><font> road salt runoff and treated wastewater from the Chicago region are the dominant sources of chlorides in the navigable sections of the Illinois River, and two major tributaries in the Chicago region. The study says that number has risen steadily since about 1960.</font></font></p><p><font><font>&ldquo;The lake doesn&rsquo;t receive very much input from stormwater from the city of Chicago,&rdquo; says Scott Twait, who works in IEPA&rsquo;s Water Quality Standards division. &ldquo;However with all the salting, all the road salt enters into the Chicago Sanitary and Ship Canal, and the Cal-Sag channel, and flows downstream to the Des Plaines River. And collecting all the runoff, the chloride levels can spike in those areas and get quite high.&rdquo;</font></font></p><p><font><font>In high concentrations, chlorides can be toxic to aquatic life. But it&rsquo;s hard to tell how many times salt runoff from Chicago has caused toxic levels of chlorides in inland waterways, because the Illinois Pollution Control Board doesn&rsquo;t classify those waters as &ldquo;General Use&rdquo; waterways. Those waters are subject to Illinois&rsquo; 500 mg/L water quality standard. Instead, IEPA regulates &ldquo;total dissolved solids&rdquo; in Chicago-area waterways, lumping together chlorides, sulfates and other chemicals for a single reading. Chloride levels have spiked above 1000 mg/L in some inland waterways &mdash; twice IEPA&rsquo;s standard for most of the state.</font></font></p><p><font><font>Chicago-area waterways are the only ones in the state that aren&rsquo;t regulated by General Use standards. As Twait explained, that&rsquo;s because they were so polluted when the standards were set that they earned their own benchmarks. (You can see IEPA&rsquo;s </font></font><a href="http://www.epa.state.il.us/water/tmdl/303d-list.html" target="_blank"><font><font>full list of impaired Illinois waterways here</font></font></a><font><font>.)</font></font></p><p><font><font><img alt="" class="image-original_image" src="http://www.wbez.org/system/files/styles/original_image/llo/insert-images/Aaron%20Stigger%20by%20Kurt%20Gerber.jpg" style="margin: 5px; float: left; height: 220px; width: 220px;" title="Aaron Stigger asked Curious City about road salt runoff. (Photo courtesy of Aaron Stigger)" />&ldquo;Back in the 70s these were the only waters that were kind of beyond repair, as to their thinking back in the 70s, so they got kind of special standards&rdquo; Twait says. &ldquo;They really had no hope for them in the future.&rdquo;</font></font></p><p><font><font>But those waters are much cleaner now. The Metropolitan Water Reclamation District of Greater Chicago, which handles and treats the region&rsquo;s combined runoff and sewer water, has improved its filtration methods. MWRD Spokeswoman Allison Fore &nbsp;says they&rsquo;ve adopted best practices suggested by the DuPage/Salt Creek Work Group for managing their roadways and facilities.</font></font></p><p><font><font>Twait says EPA is looking to bring Chicago-area waterways in line with the rest of the state&rsquo;s rivers and streams. If they update the water quality standards, he says, &ldquo;one of the things we know is that we&rsquo;ll have chloride issues in the winter time.&rdquo;</font></font></p><p><font><font>Regulators would come up with some kind of limit for chloride in Chicago-area rivers. That could make cities think twice before spreading so much road salt. It&rsquo;s much tougher for the EPA to regulate salt from so many spread-out sources (storm drains spread out across the city and suburbs) than from, say, a factory with a fallout pipe dumping salt into the river.</font></font></p><p><font><font>So our question asker Aaron Stigger is right to worry about salt runoff, but not so much in Lake Michigan. In Chicago&rsquo;s case, it&rsquo;s our inland waterways that are in trouble.</font></font></p><p><strong><font><font>Corrosive chlorides and city infrastructure</font></font></strong></p><p><font><font>Before it even gets into area waterways, salt works its way through the city&rsquo;s subterranean network of pipes. That can cause problems for the city&rsquo;s Department of Water Management, which provides drinking water to Chicago and 125 suburbs. They also deliver stormwater to MWRD for treatment.</font></font></p><p><font><font>Tom Powers, the city&rsquo;s commissioner of water management, says chlorides are at such a low concentration in Lake Michigan that his department barely takes note.</font></font></p><p><font><font>&ldquo;It would require an incredible amount of road salt to affect Lake Michigan &mdash; that&rsquo;s a very robust system,&rdquo; Powers says. &ldquo;When we test [the water], it doesn&rsquo;t even appear on what we&rsquo;re testing for.&rdquo;</font></font></p><p><font><font>The EPA&rsquo;s national drinking water standard for chloride is 250 mg/L, some 20 times higher than Lake Michigan&rsquo;s current concentration. Chicago&rsquo;s Dept. of Water Management, like many such agencies, adds water softeners that can include salt. But it&rsquo;s not enough to even approach the EPA limits.</font></font></p><p><font><font>But road salt can corrode the pipes that carry that water, exacerbating the stress that the winter freeze-and-thaw cycle puts on an aging network of water pipes that would stretch 4,500 miles if laid end to end. About 1,000 miles of those water pipes are 100 years old or older, Powers says. In 2009 the department had to repair 8,873 catch basins &mdash; more than twice last year&rsquo;s 3,647.</font></font></p><p><font><font>Development in urban areas makes the salt corrosion problem worse, by funneling more runoff into the system. Studies have correlated growth in chloride levels with the rate of urbanization, and even with miles of road in the vicinity of the waterway in question.</font></font></p><p><font><font>&ldquo;While we are right to be cautious in applying &lsquo;common sense&rsquo; to such things,&rdquo; says Stephen McCracken, who coordinates the Conservation Foundation&rsquo;s DuPage River Salt Creek Workgroup, &ldquo;in this case the relationship seems quite straightforward with salt being applied to road surfaces, increased road density means a larger salt total applied, even at a constant application rate.&rdquo;</font></font></p><p><font><font>So more development, more impervious surfaces, more runoff.</font></font></p><p><strong><font><font>A saltier lake?</font></font></strong></p><p><font><font>So not much of that salt ends up in Lake Michigan. But there is enough runoff to register an increase in Lake Michigan&rsquo;s chloride levels since Chicago first started spreading road salt.</font></font></p><p><font><font>Kim Biggs, a spokeswoman for the Illinois Environmental Protection Agency, says the current chloride levels in Lake Michigan are around 12 milligrams per liter.</font></font></p><p><font><font>That number has risen since widespread use of road salt began around 1960, according to</font></font><a href="http://www.saltinstitute.org/" target="_blank"><font><font> the Salt Institute</font></font></a><font><font>. Chloride levels in Lake Michigan rise about 0.1 mg/L each year, but they&rsquo;re still well below the U.S. Environmental Protection Agency&rsquo;s 500 mg/L standard for &ldquo;General Use waters&rdquo;. Nationally, EPA&rsquo;s criteria for chloride toxicity</font></font><a href="http://www.iowadnr.gov/portals/idnr/uploads/water/standards/ws_review.pdf?amp;tabid=1302" target="_blank"><font><font> are 230 mg/L over a four day average, or an hourly average of 860 mg/L</font></font></a><font><font>. (EPA is currently reevaluating that standard, which was first set in 1988.)</font></font></p><p><font><font>If you measure chlorides in Lake Michigan in the spring, however, you pick up all that winter road ice and runoff. Since 1980, springtime average chloride levels have risen almost 50 percent:</font></font></p><div class="image-insert-image " style="text-align: center;"><img alt="" class="image-original_image" src="http://llnw.wbez.org/styles/original_image/llo/insert-images/epa data salt.png" title="" /></div><p><br /><font><font>High chloride levels choke aquatic species that depend on a certain salinity to keep their bodies in equilibrium. Amphibians, like salamanders and frogs, are especially susceptible to chloride pollution. Many of them breed in temporary </font></font><a href="http://www.flickr.com/photos/93733769@N03/9396817314/" target="_blank"><font><font>vernal pools</font></font></a><font><font> that are cut off from other bodies water, and thus have no way to flush out excess salt.</font></font></p><p><font><font>IEPA&rsquo;s Biggs says chlorides in Lake Michigan aren&rsquo;t threatening aquatic life. &ldquo;There are not significant concerns or actions being taken to reduce chlorides in Lake Michigan as they are still reading below the water quality standard,&rdquo; she wrote in an email. &ldquo;We do not feel that salt runoff from the Chicago area is a major contributor to the chloride levels in Lake Michigan.&rdquo;</font></font></p><p><font><font>Winter deicing is the major driver of high chloride levels in Chicago&rsquo;s waterways, but wastewater treatment also contributes. In the outfall of waste water treatment plants in DuPage County, for example, chloride levels are more than ten times higher than they are in Lake Michigan. Studies by the Illinois State Water Survey and MWRD sampled the water flowing out from MWRD&rsquo;s Stickney wastewater treatment (the largest such plant in the U.S.), and found median chloride levels of 145 mg/L, compared to 8-12 mg/L in Lake Michigan.</font></font></p><p><font><font>Most of MWRD&rsquo;s contribution comes from human waste itself, which contains chlorides. They also use ferric chloride to help filter wastewater &mdash; the chemical is useful for, among other eyebrow-raising processes, &ldquo;sludge thickening&rdquo; &mdash; but are moving away from that in favor of biologically-based techniques that would replace ferric chloride.</font></font></p><p><strong><font><font>If you can&rsquo;t beet &rsquo;em ...</font></font></strong></p><p><font><font>So what&rsquo;s the city doing to cut back on its salt use?</font></font></p><p><font><font>Dept. of Streets &amp; Sanitation spokeswoman Molly Poppe says they train salt truck drivers to spread salt judiciously &mdash; that means waiting until plows have cleared most standing snow, since salt sprinkled on top of several inches of the white stuff won&rsquo;t do much. When the forecast calls for mild temperatures, salt trucks take it easy and let the weather do some of the work.<a name="video"></a></font></font></p><p style="text-align: center;"><iframe allowfullscreen="" frameborder="0" height="323" src="//www.youtube.com/embed/WphGL9fjbbo" width="575"></iframe></p><p style="text-align: center;"><em>City workers move salt at the depot at Grand and Rockwell (WBEZ/Chris Bentley)</em></p><p><font><font>The city even enlists an unusual fruit cocktail of sorts to get more out of its salt: beet juice. It&rsquo;s full of sugar, and helps lowers the freezing point of ice. Mixing salt with molasses or another sugary substance can do the same thing.

The current article addresses chemicals that are of concern to environmental agencies and that affect issuance of fish consumption advisories. The <a href="#addendum">addendum </a>addresses additional chemicals of concern.&nbsp;</em></p><p>Steve Ediger says he&rsquo;s not an avid fisherman, but he has cast a few lines. When he was growing up, his grandfather would take him fishing in Lake Geneva, Wisconsin.</p><p>About six years ago, he moved to Chicago&rsquo;s northernmost neighborhood of Rogers Park, where he sees people<a href="http://www.wbez.org/tags/fishing"> fishing</a> off Farwell Pier. It got him wondering about the fish those anglers catch, so he asked Curious City:</p><p dir="ltr" style="text-align: center;"><em>&ldquo;What would it take for Lake Michigan fish to be safe to eat?&rdquo;</em></p><p>Ediger suspects Lake Michigan fish aren&rsquo;t entirely safe to eat, and he&rsquo;s not alone. With major cities and industrial centers like Chicago, Milwaukee and Green Bay along its shores &mdash; as well as the <a href="http://articles.chicagotribune.com/2013-06-23/news/ct-met-bp-mercury-20130623_1_bp-refinery-whiting-refinery-oil-company-bp">refineries of Northwestern Indiana</a> &mdash; Lake Michigan is no stranger to pollution. To find out just how much of the stuff ends up in the fish we pluck out of the lake, I asked a few people with different angles on the situation. Turns out a lot of work goes into monitoring and disseminating information about contaminants in Lake Michigan fish. We find out which are most worrisome to fishermen and toxicologists, but also why you shouldn&rsquo;t let that scare you off eating fish entirely.</p><p><strong>A pro&rsquo;s perspective</strong></p><p>I put the question to someone who handles Lake Michigan fish every day: Joel Reiser, captain of the Chicago charter boat company<a href="http://www.bnrcharters.com/"> Brush And Roll</a>.</p><p>&ldquo;Pretty much everything is edible in Lake Michigan with moderation,&rdquo; he says. Reiser brings up to six people on chartered fishing trips in Lake Michigan, leaving from<a href="http://www.wbez.org/chicago-unveils-new-south-side-boat-harbor-99912"> 31st Street Harbor</a>. They catch chinook salmon, coho salmon, lake trout, rainbow trout, and brown trout. His crew cleans and bags up to five fish per customer (only two lake trout), which they can take home to eat.</p><p>He&rsquo;s been eating fish from Lake Michigan and elsewhere since he was a child. That might worry some people who have heard unsettling things about Lake Michigan fish. One fish market I called looking for Lake Michigan fish told me to &ldquo;try to the cancer ward.&rdquo;</p><p>With <a href="http://articles.chicagotribune.com/2013-08-07/news/ct-met-great-lakes-plastic-pollution-20130807_1_lorena-rios-mendoza-lake-michigan-toxic-chemicals">stories of polluted waters</a> swirling, Reiser watches out for government-issued fish advisories and eats seafood in moderation. But he says fish from any waters can contain contaminants.</p><p>&ldquo;I&rsquo;ve never heard of anyone growing a third eye, you know, some of the jokes that are out there,&rdquo; he says. &ldquo;So I believe that it&rsquo;s safer. I believe the government does put higher standards on it, just as a safety precaution just to cover &mdash; no pun intended &mdash; their own tail.&rdquo;</p><p>It turns out, Reiser&rsquo;s basically right. In casting about for an answer to Ediger&#39;s question, we found out Lake Michigan&rsquo;s pollution problems aren&rsquo;t the whole story. The horror stories are overblown, but they&rsquo;re rooted in truth.</p><p><strong>(Fish) food for thought</strong><a href="http://www.scribd.com/doc/210637870/Lake-Michigan-fish-How-many-should-you-eat" target="_blank"><img alt="" class="image-original_image" src="http://llnw.wbez.org/styles/original_image/llo/insert-images/big fish graphic 2.png" style="float: right; height: 882px; width: 320px;" title="Click to download a printable version. (Graphic by Logan Jaffe/WBEZ)" /></a></p><p>Tom Hornshaw, a toxicologist with the Illinois Environmental Protection Agency&rsquo;s &ldquo;<a href="http://www.epa.state.il.us/water/surface-water/fish-contaminant-mon.html">fish contaminant monitoring program</a>,&rdquo; helps gather data that goes into those government advisories. Since 1974, the Illinois Department of Natural Resources and IEPA have nabbed fish (mainly bass, channel catfish and carp)<a href="http://mercnet.briloon.org/projects/IL_EPA_-_llinois_Fish_Contaminant_Monitoring_Program/144/"> from 500 locations</a> in Illinois for contaminant testing. I asked Hornshaw point-blank: Is it safe to eat fish from Lake Michigan?</p><p>&ldquo;Yeah,&rdquo; he says, &ldquo;as long as you follow the various advisories that have been issued for Lake Michigan fish.&rdquo;</p><p>If you&rsquo;re wondering what Captain Reiser meant by &ldquo;moderation,&rdquo; you might start with the<a href="http://www.ifishillinois.org/regulations/consumption.html"> general fish consumption advisory</a> from the Illinois Department of Public Health.</p><p>State agencies keep<a href="http://www.idph.state.il.us/envhealth/fishadvisory/index.htm"> a running list of current fish advisories statewide</a>, which vary by species and body of water. They also change over time. On a <a href="http://www.idph.state.il.us/envhealth/fishadvisory/lakemichigan.htm">page that&#39;s specific to Lake Michigan catch</a>, the agency provides warnings for&nbsp;10 fish species. The DNR doesn&rsquo;t recommend you eat any of them more than once a week, and some come with the unequivocal advice: &ldquo;<strong>Do Not Eat.</strong>&rdquo; This applies to lake-caught carp and channel catfish.</p><p>The advisories vary based on the fish&rsquo;s size, in some cases. Take the yellow perch,<em> Perca flavescens</em>. Fish less than 11 inches long, the Illinois DNR says, should be eaten at most once per week. But you should only eat perch larger than 11 inches once per month. Likewise lake trout, a popular sport fish can that grow up to three feet long, carries three tiers of advisories: less than 25 inches? One meal per month; 25-29 inches? Six meals per year; larger than 29 inches? Do not eat.</p><p>If you fish in Wisconsin, use that state&rsquo;s<a href="http://dnr.wi.gov/FCSExternalAdvQry/FishAdvisorySrch.aspx"> online query tool</a> to check on the water you&rsquo;ll be fishing. Indiana, too,<a href="http://www.in.gov/isdh/23650.htm"> updates its fish consumption advisories online</a>.</p><p><strong>PCBs: What&rsquo;s all the fuss about?</strong></p><p>One of the major culprits are a group of chemicals known as PCBs. Polychlorinated biphenyls<a href="http://www.idph.state.il.us/envhealth/fishadvisory/fishadvisory_qa_pcb.htm"> are a group of man-made chemicals useful in a variety of industrial processes</a>, including the insulation and cooling of electrical equipment. EPA banned their use in 1979, after it was widely recognized PCB pollution had caused skin conditions and immune system disorders. Studies have also linked the chemicals to cancer. We produced more than one billion pounds of the stuff in the U.S., about half of which made its way into the environment.</p><p>They take a long time to break down, so PCBs are still prevalent in the environment.<a href="http://www.idph.state.il.us/envhealth/fishadvisory/waukegannorthharbor.htm"> There is a specific advisory for Waukegan North Harbor</a>, where Outboard Marine Corp.<a href="http://newssun.suntimes.com/news/14980816-418/waukegan-harbor-pcb-mess-finally-getting-scrubbed.html"> dumped PCBs</a> as a byproduct of their manufacturing process. That cleanup is ongoing.<a href="http://articles.chicagotribune.com/2012-09-07/news/ct-met-waukegan-harbor-cleanup-20120907_1_susie-schreiber-cleanup-sites-epa-remedial-project-manager"> EPA is dredging the harbor</a>, a <a href="http://www.epa.gov/superfund/sites/" target="_blank">Superfund site</a> once called the &ldquo;world&rsquo;s worst PCB mess.&rdquo;</p><p>But PCB pollution continues long after its source is cut off. PCBs still find their way into the<a href="http://www.wbez.org/tags/great-lakes"> Great Lakes</a> through a process called<a href="http://www.epa.gov/glindicators/air/airb.html"> atmospheric deposition</a>. They travel around the world through the atmosphere, falling out of the sky at high latitudes. That&rsquo;s why scientists have found high levels of the stuff in the Arctic, thousands of miles from the factories that pumped out PCBs in the 1970s.</p><p>At this point Hornshaw, the EPA toxicologist, says atmospheric deposition is probably the primary source of PCBs in the<a href="http://www.wbez.org/tags/great-lakes"> Great Lakes</a>. He says there&rsquo;s a simple, one-word answer for what it will take for Lake Michigan fish to become safer for consumption.</p><p>&ldquo;Time,&rdquo; he says. Not 10 years, but less than 100. These chemicals take a long time to break down, but they&rsquo;re not invincible. Beth Murphy, who manages EPA&rsquo;s Great Lakes Fish Monitoring and Surveillance program, passed along this graphic showing PCB declines against a 1994-95 baseline (the red line):</p><p><img alt="" src="http://www.wbez.org/system/files/styles/original_image/llo/insert-images/trout%20chart.jpg" style="height: 465px; width: 620px;" title="" /></p><p>The graph suggests that by 2035, assuming progress continues, you should be able to eat all the Great Lakes lake trout filets that you want without fear of PCBs.</p><p>Lake and river sediments are especially good at holding onto PCBs, so bottom-dwelling fish tend to have higher levels (hence the &ldquo;Do Not Eat&rdquo; advisory on carp and channel catfish in Lake Michigan). PCBs also accumulate in fatty tissues, so it&rsquo;s important to filet wild-caught fish properly before eating them.<img alt="" class="image-original_image" src="http://www.wbez.org/system/files/styles/original_image/llo/insert-images/fish%20cutting.gif" style="float: left;" title="" /></p><p>PCBs aren&rsquo;t very soluble in water, so swimming isn&rsquo;t going to result in dangerous exposure.</p><p><strong>Getting the good stuff</strong></p><p>It turns out Captain Reiser&rsquo;s suspicion that government agencies were covering &ldquo;their own tail&rdquo; is correct.</p><p>&ldquo;The advisories may be overprotective for women beyond childbearing age and for adult men,&rdquo; reads<a href="http://www.idph.state.il.us/envhealth/fishadvisory/fishadvisory_qa_pcb.htm"> an FAQ from the Illinois Department of Public Health</a>. That&rsquo;s especially true for<a href="http://www.epa.gov/hg/exposure.htm"> mercury &mdash; a potent pollutant found in fish from Lake Michigan and around the world</a>.</p><p>Fetuses, nursing babies and young children are especially vulnerable, so the advisories are drafted with a low tolerance for risk. Mercury can severely hinder development of the fetal nervous system. EPA found<a href="http://water.epa.gov/scitech/swguidance/fishshellfish/fishadvisories/technical.cfm#tabs-4"> mercury levels in women of childbearing age dropped 34 percent from a survey conducted in 1999-2000</a>, but it&rsquo;s still a concern.</p><p>But eating fish has a lot of health benefits, too, so long as you don&rsquo;t exceed the advisories. Eight Great Lakes states are two years into a study funded by the<a href="http://www.wbez.org/tags/great-lakes"> Great Lakes</a> Restoration Initiative, weighing the benefits of eating fish against the risks. &ldquo;We&rsquo;re trying to come up with ways of incorporating the benefits of eating fish along with the deleterious effects,&rdquo; Hornshaw says, &ldquo;so we can have a more focused advisory.&rdquo;</p><p>Pat McCann, a fish advisory specialist with Minnesota&rsquo;s Department of Public Health says it&rsquo;s important to keep in mind the big picture.</p><p>&ldquo;The benefits do outweigh the risks if you eat fish that are low in contaminants,&rdquo; McCann says. &ldquo;So the challenge is to get people information about which fish are low in contaminants, and get it to them in a way that&rsquo;s understandable and that they can adopt in their normal life.&rdquo;</p><p>A lot of people swear off fish altogether, but McCann says that&rsquo;s actually counterproductive. Take the group of people most sensitive to mercury contamination: pregnant women. Mercury impairs neurological development in fetuses. But the McCann says that doesn&rsquo;t mean women should avoid all fish entirely.</p><p>&ldquo;Women of childbearing age and pregnant women need to eat fish, because fish have Omega-3 fatty acids, and other good nutrients, and it&rsquo;s a good source of protein,&rdquo; she says. &ldquo;And so those things are good for the baby. So if they stop eating fish that&rsquo;s a negative thing.&rdquo;</p><p>Concentrations of mercury and PCBs are above guidelines for walleye and lake trout in all of the Great Lakes. Mercury levels were getting worse in Lakes Superior, Huron and Erie when <a href="http://binational.net/solec/sogl2011/sogl-2011-technical-report-en.pdf">EPA and Environment Canada released their 2011 &quot;State of the Great Lakes&quot; report</a>.</p><p><strong>Reeling it in</strong></p><p>One place you&rsquo;ll find Great Lakes fish on sale in Chicago is Market Fisheries at 7129 S. State St., in the<a href="http://www.wbez.org/tags/greater-grand-crossing"> Greater Grand Crossing</a> neighborhood. They&rsquo;ve been owned and operated by the Brody Family since 1957.</p><p>Curtis Alexander, the market&rsquo;s manager, shows me around. The market&rsquo;s busy. People pull numbers and step up to order catfish or perch, while an employee behind the counter scales and hacks up fish.</p><p>Alexander says their suppliers are mostly based in Canada, so they don&rsquo;t sell Lake Michigan fish. But they&rsquo;ll gladly clean your catch.</p><p>&ldquo;A lot of time I clean fish that people go and catch from Lake Michigan,&rdquo; he says. &ldquo;You got the yellow lake perch over there, you got the little bluegills, walleye pike, you know bigmouth bass &mdash; there&rsquo;s a lot of fish that they catch from Lake Michigan. People go fishing, they bring them in here, sometimes we clean it up for them.&rdquo;</p><p>No one brings in fresh-caught fish from Lake Michigan while I&rsquo;m there. But trout fishing season in Illinois starts April 5, and Alexander may have new customers soon. IDNR added four new areas for rainbow trout fishing this year, including Chicago&rsquo;s Wolf Lake&mdash;<a href="http://www.wbez.org/series/curious-city/where-can-you-hunt-chicago-108954">one of two hunter-friendly oases in the city proper</a>.</p><p>Our question-asker, Steve Ediger, knows a few people who might take advantage of that new fishery. In an informal survey of his fishing friends, Ediger found that concerns over PCBs and mercury aren&rsquo;t deal-breakers for avid anglers.</p><p>&ldquo;I&rsquo;ll tell you the one thing everybody says,&rdquo; Ediger says. &ldquo;They were less suspect of the fish they catch than the fish they get in the supermarket.&rdquo;</p><p>Mercury and PCB pollution are problems for fisheries all over the world &mdash; not just Lake Michigan. Clean-up efforts here have come a long way, but new pollutants could set us back. A BP refinery in Northwest Indiana <a href="http://articles.chicagotribune.com/2013-06-23/news/ct-met-bp-mercury-20130623_1_bp-refinery-whiting-refinery-oil-company-bp">came under fire last year</a> when it missed a federal deadline to put in place new pollution controls for mercury (state regulators gave them an exemption).</p><p>And if <a href="http://www.wbez.org/tags/asian-carp">the threat of invasive species like Asian carp</a> proves as devastating as some studies predict, Great Lakes fisheries could collapse whether or not we continue to clean up the water.</p><p>So, a corollary to Tom Hornshaw&rsquo;s one-word answer to our question: What will it take to make Lake Michigan fish safe to eat? Time, and our attention.</p><p dir="ltr"><strong><a name="addendum"></a>Addendum: other chemicals</strong></p><p dir="ltr">Mercury and PCBs are the major chemicals that Illinois&rsquo; state EPA tests for and regulates, but <a href="http://www.epa.gov/greatlakes/monitoring/fish/">there are other contaminants worth considering</a>.</p><p dir="ltr">Many other chemicals meet the two main criteria for raising fish contaminant concerns: <a href="http://www.michigan.gov/mdch/0,1607,7-132-54783_54784_54785_54800-256866--,00.html">they&#39;re bioaccumulative and persistent</a>. That means they build up in the tissues of aquatic organisms, and they stick around. They can broadly be categorized by the term the EPA uses, &ldquo;<a href="http://www.epa.gov/international/toxics/pop.html">persistent organic pollutants</a>.&rdquo;</p><p dir="ltr">Besides mercury and PCBs, a few other common contaminants fit the bill: pesticides such as DDT, chlordane, and dieldrin; and dioxins, a carcinogenic group of chemicals created in the course of many industrial processes. (Dioxins are chemically similar to PCBs, which could themselves be counted under that blanket term.)</p><p dir="ltr">More recently, Great Lakes environmental agencies <a href="http://www.epa.gov/grtlakes/monitoring/fish/pbde.html">have tracked the dilution of another potentially harmful contaminant</a>. A group of flame retardant chemicals known as PBDEs (polybrominated diphenyl ethers) were phased out starting in 2004. Measurements by Environment Canada <a href="http://www.epa.gov/grtlakes/monitoring/fish/pbde.html">show</a> declines in PBDE concentrations across the Great Lakes, including Lake Michigan, but Illinois EPA doesn&rsquo;t track PBDEs in fish. As toxicologist Tom Hornshaw explains, the reason isn&rsquo;t lack of concern &mdash; it&rsquo;s lack of funding.</p><p dir="ltr">&ldquo;Currently PBDEs are not addressed in our fish advisory program&mdash;our lab is not set up to do PBDEs and it would require purchase of an expensive piece of equipment to analyze for them,&rdquo; Hornshaw writes in an email.</p><p dir="ltr">It&rsquo;s important to note in this addendum that the chemicals we&rsquo;re phasing out now don&rsquo;t disappear immediately. That&rsquo;s why they call them persistent pollutants. PCBs, DDT and other chemicals in the Great Lakes are contaminants largely inherited from a time roughly 50 years ago. We have to wonder what legacy today&rsquo;s garbage will have on future Great Lakes residents.</p><p dir="ltr">Already <a href="http://www.reuters.com/article/2013/07/31/us-usa-pollution-greatlakes-idUSBRE96U03120130731">tiny plastic beads pose a threat</a> to fish health and environmental quality in the region.</p><p dir="ltr"><em><a href="http://cabentley.com/">Chris Bentley</a> is a reporter for WBEZ&rsquo;s Curious City, and a freelance journalist.

Chicago is only the 34th most trafficked port in the country based on total cargo, but it is the second most popular in the Great Lakes (Duluth-Superior on the Minnesota-Wisconsin border is 21st in the country, with 35 million tons in 2011 compared to Chicago&rsquo;s 20 million). A lot of the bulk freight traffic at Chicago&rsquo;s port actually moves between the city and inland ports, staying out of the Great Lakes entirely. In 2011 Chicago handled about five times as much domestic freight as foreign.</p><p>But with highways, railroads and two major airports nearby, the port of Chicago could support more waterborne movement of cargo.
